Peacock gudgeon (Tateurndina ocellicauda) – freshwater aquarium fish from the family of eleotomatoes.
He lives in Papua New Guinea. It lives in shallow streams, ponds and rivers. Found in tropical forests.
Characteristics and disposition
The Color Head is 7.5 cm long.
Adult males are more colorful and slightly larger than females, their head is clearly larger and distinct from the body. Females are rounder and have a yellowish tinge on the belly. Juveniles can be distinguished by the anal fin. Most females have a dark band that runs along the outer edge of this fin. The fish shows territorialism towards its own species, but it does not fight fiercely for territory, but only stiffens and stiffens its fins against its rivals.
In nature, it lives in large, loose-swimming groups, most often close to the bottom.
Nutrition and feeding
Fish prefer live and frozen food, the diet can be supplemented with dry food.
For a couple, a 50-liter aquarium is enough, with a dark substrate, dense vegetation (also floating), decorations in the form of roots and stones. In such a tank, the fish will be less skittish. They require clean water and frequent changes.
The water current should not be too strong. They are good jumpers, so a cover is essential. They can stay with Rainbowfish in the biotope aquarium. In sociable, for example, tetrami, kiryskami , razborami, otoskami and other small, peaceful fish. They can be kept with other territorial fish, such as the ramireza cichlid, but in a correspondingly larger tank.
Colored headers are relatively easy to reproduce . Fish spawn in caves and crevices. In the aquarium, we can use, for example, pieces of PVC pipes, pots, nut shells. Clumps of plants will also be useful, providing the fish with additional shelter. It is best to buy 6-8 young individuals that will naturally pair up.
Before the planned spawning, we give the fish live or frozen food and change about 20% of the water each week. It should spawn soon. When the female’s belly is clearly larger, the male chooses a place and prepares the nest. As soon as the female swims to the grotto, the male begins to tense up and flap her fins, attracting her in this way. Sometimes she drives the females, nudging her towards the entrance.
If the male’s courtship is successful, the female flows into the cave and lays eggs in it. On average, about 30-40 pieces. Roe is attached with small “threads” in a similar way as in the Clownfish. After laying the eggs, the female is chased away by the male. This is where it is best to catch it.
The male looks after the nest by fanning the roe grains with its fins, thus ensuring a supply of fresh, oxygenated water. Hatching occurs within 24-48 hours, after which the male stops caring for the eggs. The fry should be separated into a separate tank, otherwise they will be eaten. After 2-4 days, the young fish begin to swim in search of food. They are easy to raise, are relatively large and can be immediately fed, for example, with micro nematodes and brine shrimp larvae.
